As Pepper has gotten older I've noticed that he's getting more white hairs all over his body. He had to be shaved on part of his belly and his bottom area when he was sick last year. His hair grew back with a lot of white in it. I asked the vet about this and he said that this often happens with black cats but he doesn't know the reason. So if I had Pepper shaved for the summer I think his fur would grow back like this so he'd look like a different cat. I don't think that Basil is a tuxedo cat because I think that they start out with black and white fur when they are born. I don't think that they start getting the white fur as they get older but I could be wrong.
